Photographic apparatus for use with mechanically
fireable flash structures

ABSTRACT

PHOTOGRAPHIC APPARATUS, SUCH AS A CAMERA, FOR SENSING THE CONDITION OF AND FOR FIRING A PERCUSSIVE FLASH DEVICE. THE FLASH DEVICE INCLUDES A LAMP AND A STRIKER (7) LODGED IN AN ENERGIZED POSITION FROM WHICH IT IS RELEASABLE TO FIRE THE LAMP. THE APPARATUS INCLUDES AN ACTUATING MEMBER (102) MOVBLE FROM A FIRST POSITION RETRACTED FROM THE FLASH DEVIE, TO A SECOND POSITION FOR SENSING AND ENGAGING AN ENERGIZED STRIKER IN THE DEVICE, AND TO A THIRD POSITION FOR RELEASING THE STRIKER TO FIRE THE DEVICE. THE MEMBER IS MOVED FROM THE FIRST POSITION TO THE SECOND POSITION IN RESPONSE TO INITIAL DEPRESSIONOF THE CAMERA BODY RELEASE. THEREAFTER, MOVEMENT FROM THE SECOND POSITION TO THE THIRD POSITION AND BACK TO THE FIRST POSITION IS EFFECTED BY TRANSLATION OF A DRIVER FROM AN ENERGIZED CONDITION TO A RELEASED CONDITION.
